LBB 1950/10 Plena Tabletop Unidirectional Condenser Microphone www.boschsecurity.com
The Plena tabletop microphone is a stylish, highquality tabletop unidirectional condenser microphone, mainly intended for making calls in a public address system. Its heavy metal base and rubber feet ensure stability on any flat surface. The special design also allows the unit to be neatly flush-mounted in desktops. Functions The PTT-key (press-to-talk), not only switches on the microphone, but also provides priority contacts, that are compatible with the Plena range of amplifiers. The switching characteristic of the PTT-key can be configured internally for PTT-mode (on as long as pressed) or toggle-mode (press to switch on, press again to switch off). It is equipped with a fixed, flexible 2 m cable and a 5‑pin DIN connector for the balanced signal and the priority contacts. If the priority contacts are not required, the microphone can be connected to amplifiers with 3‑pin XLR-inputs, using the DIN to XLR adapter.
